How to help FGLRX detect a device
- by user113416
I have HD 4850 card, Ubuntu 12.10 and installed legacy drivers using makson96 ppa.
The issue is, that FGLRX can not detect my device and loads vesa bios. I had the same problem on ubuntu 11.10, 12.04 versions. I want to manually help fglrx find a matching device to load as it shoudld do.
It is interesting, why does fglrx search for a device in a PCI:0@1:0:1 Bus?
in xorg.cof different bus is indicated:
Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"
EndSection
fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Radeon HD 4800 Series
OpenGL version string: 3.3.11653 Compatibility Profile Context
Here is a part of my xorg log:
[ 3.846] (II) VESA: driver for VESA chipsets: vesa
[ 3.846] (II) FBDEV: driver for framebuffer: fbdev
[ 3.846] (++) using VT number 7

Thanks in advance.
